I believe SWDADA is wanting to know if components in an assembly can be grouped together to form a new subassembly within the main assembly. Likewise, can a subassembly be dissolved into individual components within a main assembly.
In SolidWorks, there are specific commands to do this. This is different from moving components or subassemblies up / down the tree structure. I do not know if this exists in Pro-E, or if it does is it part of the Advanced Assembly Extension (AAX) module?
To simulate assembly motion, select from the top menu: Applications --> Mechanism
Below is an overview of Mechanism design from the Pro-E help menu:
About Mechanism Design Kinematics
If you do not have a Mechanism Dynamics option license, only
the kinematics menus are available when you start Mechanism Design. In a
kinematics study, you can define your mechanism, make it move with servo motors,
and analyze the motion without reference to forces acting on the system. Use
kinematics to observe the movement of your mechanism, and to measure the change
in position, velocity, and acceleration of the bodies. See the workflow
illustration for a summary of the process you can use to study your model with
Mechanism Design kinematics.
There are two kinematics tutorials to help you become
familiar with Mechanism Design. The first tutorial leads you through a study of
a single piston assembly, including building the model, applying a servo motor,
checking the motion of the model with the drag functionality, running an
analysis, and viewing the results. The second tutorial creates a four-bar
linkage, then sets motion axis limits, uses time-conditional servo motors, and
demonstrates trace curves.
